Manifest settings

Use a JSON-formatted manifest file to configure an application or platform for the OpenFin environment.

The OpenFin Runtime requires each application or platform to provide a JSON formatted manifest file with configuration information. This manifest file defines the visual properties of the app, its dependencies, and other deployment settings. The developer is in control of the app development process and how this file is hosted and configured. Both the openfin-cli and OpenFin RVM use a manifest file to launch applications as well as to make use of other configuration data.

Many of the properties that can be used in a manifest are defined as types in the OpenFin API. Follow links to the API reference for complete details.
